Thanks for the suggestion but theta is, in fact, a vector-valued function. It acts on the elements of the input list / vector in a non-linear and non-trivial way. So I'm looking for ways to craete a function (perhaps wrapping BuiltinFunction) that can recognize and evaluate vectors over SR. The issue is that theta currently can only evaluate numerical input. (Over ComplexField.) There's a lot of numerical approximation going on so simply feeding it symbolic types isn't going to work. Hence, the need for some sort of wrapper around this numerical theta that will deal with symbolic input appropriately. -- Chris -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
